Title
(EN) CURVED PANEL MEMBER
(FR) ÉLÉMENT DE PANNEAU INCURVÉ
(JA) 曲面パネル部材
Abstract
(EN)
This curved panel member comprises a curved metal panel, and a reinforcement member that is joined to the curved panel and that comprises a plurality of FRP layers containing continuous fiber. Each of the plurality of FRP layers has one fiber direction. At least one of the plurality of FRP layers has a fiber direction different to that of the other layers. In the plurality of FRP layers, the proportion of layers in which the angle difference of the fiber direction is 30° or greater is at least 15% of all layers. Relationship (1) is met when, with respect to the respective fiber directions of the FRP layers of the reinforcement member joined to the curved panel, the 0° direction component and the 90° direction component are calculated using a trigonometric function, where 0° is defined as the maximum principle curvature direction of the curved panel and 90° is defined as the direction orthogonal to the 0° direction.

La présente invention concerne un élément de panneau incurvé comprenant un panneau métallique incurvé et un élément de renforcement qui est assemblé au panneau incurvé et qui comprend une pluralité de couches FRP contenant une fibre continue. Chacune de la pluralité de couches FRP présente une direction de fibre. Au moins l'une de la pluralité de couches FRP présente une direction de fibre différente de celle des autres couches. Dans la pluralité de couches FRP, la proportion de couches dans laquelle la différence d'angle de la direction de fibre est de 30° ou plus est d'au moins 15 % de toutes les couches. La relation (1) est satisfaite lorsque, par rapport aux directions de fibre respectives des couches FRP de l'élément de renforcement joint au panneau incurvé, le composant de direction de 0° et le composant de direction de 90° sont calculés au moyen d'une fonction trigonométrique, où 0° est défini comme la direction de courbure principale maximale du panneau incurvé et 90° est défini comme la direction orthogonale à la direction 0°.
